You could use a timing light to help make the adjustment more accurate.

That's exactly how it used to be done. It is still a mechanical adjustment. so yes. the day of no spark plus and digital firmware to do adjustments are close, but not here yet. twist on.

Reset timeing on 1990 subaru legacy


Hi Jeff, The timing is set and controlled by the computer, but you can manually rotate the distributor. When I had pulled the distributor out of one of my suby's, it got bumped and rotated. I simply inserted it and hooked up the plug, tried to start the car and if it didn't start, re pulled the distributor, rotated the gear by one notch over and over again, until I got it right. If you recently changed the belt and something got moved, I always suggest a Chilton or Haynes manual, either and both have gotten me where I needed to be with my suby's. Good luck Jeff!

Distributor not rotating after changing the fuel pump on 3.8 chevy


The 3.8 liter engine has a timing chain. The distributor shaft should be turning if your timing chain is still intact. Have you pulled it out and reinstalled it? Maybe you did not get it seated right.
This must not be a '99 Silverado as shown in the heading? Give a reply back, and explain please. You replaced a fuel pump in the gas tank, and now the distributor shaft is not rotating? There is no plausible relation between the two-please explain.

How to install a distributor in a 93 mustang gt


Removal;
Rotate the engine until the No. 1 piston is on top dead center of its compression stroke.Remove The distributor cap and then mark where the rotor is pointing on the side of the distributor with some white out or anything that you might be able to see when replacing the distributor back into position. Disconnect the TFI module by pressing the catch and pulling on it.Loosen and remove the distributor hold-down bolt.The distributor should slide straight out. It is also necessary to remove the distributor to change the TFI module if you had to do this in a separate operation.


Install:
Rotate the distributor shaft so the rotor points toward the mark on the distributor housing that you made previously.Install the distributor hold-down bolt tighten slightly. Recheck the initial timing after installing the distributor cap. Tighten the hold-down bolt and recheck the timing. Adjust again if necessary.Thank you for your questions

FIRING ORDERS
NOTE: To avoid confusion, tag and remove the spark plug wires
one at a time, for replacement.

If a distributor is not keyed for installation with only one orientation, it
could have been removed previously and rewired. The resultant wiring would hold
the correct firing order, but could change the relative placement of the plug
towers in relation to the engine. For this reason it is imperative that you
label all wires before disconnecting any of them. Also, before removal, compare
the current wiring with the accompanying illustrations. If the current wiring
does not match, make notes in your book to reflect how your engine is wired.

Need to know how to install a new distributor and the firing order for a 4 cyl


Firing order is 1342. #1 cylinder is closest to front. (By pulleys)



See Figures 1, 2, 3 and 4
Engine Not Rotated
  1. Disconnect the negative battery terminal.
  2. Turn the engine over until No. 1 cylinder is at TDC of the compression stroke.
  3. Remove the distributor cap. Remove the wire harness connected to the side of the distributor.
  4. Mark the position of the distributor base in relation to the engine block with white paint or other suitable marking material, for reference when reinstalling the distributor.
  5. Loosen and remove the distributor hold-down bolt and clamp.
  6. Carefully begin lifting the distributor up and out. Once the shaft is clear of the engine compartment, inspect the shaft for cracks in the O-seal, the condition of the shaft drive gear and any other part which could lead to distributor problems in the future.

To install:
  1. Check to make sure the engine is still at TDC. Inspect distributor shaft hole to make sure it is free of dirt.
  2. Rotate distributor shaft until the painted mark on rotor is pointing toward painted mark on engine block made during removal.
  3. Continue rotating rotor slightly so leading edge of the vane is centered in vane the switch stator assembly.
  4. Dip entire distributor gear in engine assembly lubricant D9AZ-19579-D or equivalent.

If installing a new distributor, ALWAYS add engine assembly lubricant to the engine oil by pouring it through distributor hole onto the camshaft gear. Run engine at idle for at least five minutes before driving.
  1. Rotate distributor in block to align leading edge of vane and vane switch stator assembly. Verify rotor is pointing at No. 1 mark on distributor base.

If vane and vane switch stator cannot be aligned by rotating distributor in cylinder block, remove distributor enough to just disengage distributor gear from camshaft gear. Rotate rotor enough to engage distributor gear on another tooth of the camshaft gear.
  1. Install the distributor retaining bolt and tighten so the distributor can just barely be moved.
  2. Install the distributor cap and, tighten screws to 18-23 inch lbs. (2.0-2.6 Nm).
  3. Reconnect battery cable. Start vehicle, and check timing. If timing needs adjustment, refer to the Ignition Timing section.
  4. After timing has been set, tighten distributor hold-down bolt to 17-2 ft. lbs. (23-34 Nm).

Engine Rotated with Distributor Removed
  1. If the crankshaft was rotated while the distributor was removed, the engine must be brought to TDC on the compression stroke of the No. 1 cylinder.
  2. Remove the No. 1 spark plug. Place a finger over the hole and rotate the crankshaft slowly in the direction of normal rotation until engine compression is felt.
  3. When engine compression is felt at the spark plug hole, indicating that the piston is approaching TDC, continue to turn the crankshaft until the timing mark on the pulley is aligned with the 0 mark on the engine front cover.
  4. Turn the distributor shaft until the ignition rotor is at the No. 1 firing position.
  5. Rotate distributor shaft so the blade on rotor is pointing toward paint mark on distributor base made during removal.
  6. Continue rotating rotor slightly so leading edge of the vane is centered in vane switch stator assembly. Verify rotor is pointing at No. 1 mark on distributor base.

If vane and vane switch stator cannot be aligned by rotating distributor in cylinder block, remove distributor enough to just disengage distributor gear from camshaft gear. Rotate rotor enough to engage distributor gear on another tooth of the camshaft gear.
  1. Install the distributor retaining bolt and tighten so the distributor can just barely be moved.
  2. Install the rotor and distributor cap and connect all wiring. Tighten distributor cap to 18-23 inch lbs. (2.0-2.6 Nm).
  3. Reconnect battery cable. Start vehicle, and check timing. If timing needs adjustment, refer to the Ignition Timing section.
  4. After timing has been set, tighten distributor hold-down bolt to 17-2 ft. lbs. (23-34 Nm).

I dont know how to put my spark plug wires in my car


firing order 1-4-2-5-3-6

  1. Insert each ignition wire on proper terminal of distributor cap . Ensure ignition wires are properly seated on the terminals. The No. 1 terminal is identified on distributor cap .
not sure if #1 cylinder is on the front right or front left. Call a dealer.
d8a0dc7.gif
Installation
Before installing distributor , visually inspect distributor . Inspect the O-ring. It should fit tightly and be free of cuts. The drive gear should be free of nicks, cracks and excessive wear. Rotate distributor drive shaft. It should move freely, without binding.
  1. To install distributor correctly, No. 1 piston (6108) must be at Top Dead Center (TDC) of compression stroke. Remove No. 1 cylinder spark plug (12405) and rotate crankshaft (6303) clockwise until No. 1 piston is on the compression stroke.
  1. With No. 1 piston on compression stroke, align timing pointer with TDC on the crankshaft damper.
  1. Align locating boss on distributor rotor with hole on armature. Fully seat distributor rotor on distributor shaft.
  1. Rotate distributor shaft so blade on distributor rotor is pointing toward mark on distributor base that was previously made in Step 2 of the Removal procedure.
  1. While installing, continue rotating distributor rotor slightly so leading edge of the vane is centered in vane switch stator assembly.
  1. Rotate distributor in engine front cover to align leading edge of vane and vane switch stator assembly. Verify distributor rotor is pointing at No. 1 mark on distributor base. If vane and vane switch stator cannot be aligned by rotating distributor in engine front cover , remove distributor enough to just disengage distributor gear from camshaft gear. Rotate distributor rotor enough to engage distributor gear on another tooth of camshaft gear. Repeat Step 1 if necessary.
  1. Install distributor hold-down clamp and bolt. Tighten bolt, but leave it loose enough to rotate distributor .
  1. Install distributor cap , No. 1 spark plug and ignition wires. Check that ignition wires are securely connected to the distributor cap and spark plugs . Tighten distributor cap hold-down screws to 2.0-2.6 Nm (18-23 lb-in).
  1. Reconnect distributor to engine control sensor wiring .
  1. Set initial engine ignition timing according to procedures found in Section 8A of the Powertrain Control/Emissions Diagnosis Manual.
  1. After engine ignition timing is set, tighten distributor hold-down bolt on to 20-30 Nm (15-22 lb-ft).
  1. Recheck initial engine ignition timing. Adjust if necessary.
